A linear bound for a connectivity partition in graphs
Jia Zhou, Jin Yan, Yunshu Gao
Kühn and Osthus proved that, for every positive integer , every -connected graph has a partition such that and are -conne…
Observation of REBCO delamination in the resistive insulation nested coils
Jun Lu, Iain Dixon, Kwangmin Kim +2
The REBCO coated conductor has the potential to be widely used in ultrahigh field magnets. It is well known, however, that it is not mechanically strong against delamination in the…
Study of delamination in REBCO coated conductor by transmission electron microscopy
Yan Xin, Jun Lu, Ke Han
Delamination strength of REBCO is very important for its applications in large magnet projects. This work presented the transmission electron microscopy (TEM) investigation of the…
Residual resistance ratio of Cu stabilizer in commercial REBCO tapes
Jun Lu, Yan Xin, Vince Toplosky +6
Residual resistance ratio (RRR) of Cu stabilizer in REBCO coated conductor is an important design parameter for REBCO magnets. In this work, we measured RRR of electroplated Cu sta…
Thermal conductivity of REBCO tapes with different stabilizers from 4.2 to 200 K
Jun Lu, Yan Xin, Yifei Zhang
REBCO coated conductor is a high temperature superconductor that has a wide range of applications, one of which is the current leads of magnet systems. In the design of current lea…
